A teacher wants to estimate the mean time (in minutes) that students take to go from one classroom to the next. His research assistant uses the sample time of 36 students to report the confidence interval as [8.20, 9.80]. (You may find it useful to reference the t table.) a. Find the sample mean time used to compute the confidence interval. (Round final answer to nearest whole number.)   probability=   (ANSWER IS NOT 0.005 or 0.1)

Using the following distribution, answer the questions below: Ages        frequency20-25            926-31            732-37            338-43          1144-49          1050-55            8 4) Prepare a frequency polygon to display the data from the exercise above

Use the following digits to construct a frequency distribution and then a histogram. Use classes of 0, 1, 2, 3 , 4 , 5 , 6, 7 , 8, 9 (note that each class only contains one value) 000000112333455555555555566888899

Use the Histogram tool to develop a frequency distribution and histogram for the number of months as a customer of the bank in the data below. Compute the relative and cumulative relative frequencies and use a line chart to construct an ogive.   Complete the frequency distribution for the months as a​ customer, and compute the relative and cumulative relative frequencies. ​(Type integers or decimals rounded to three decimal places as​ needed.)
